Jenny's Lantern

Jenny's Lantern is an area of moorland in north Northumberland, England, taking its name from an 18th-century 'eye-catcher' folly sited towards the top of a small promontory hill above the River Aln.

Situated on the southern slope of the Jenny's Lantern area is an Iron Age hillfort, overbuilt by and adjoined to a larger and very well preserved Romano-British stone-built settlement and field system.

[2][3] The local penchant for follies extended to the dominant landowner, Hugh Percy, 1st Duke of Northumberland who commissioned the Ratcheugh Observatory before 1770,[4] and whose 1781 Brizlee Tower[5] sits roughly opposite, across the Aln, from Jenny's Lantern.

[citation needed] Jenny's Lantern hillfort is an Iron Age defended settlement, undated, but falling within a style dating from circa 700BCE to 100CE.

[8][7] The hillfort and settlement site has been placed on the Heritage at Risk Register, as its condition is found to be "generally unsatisfactory with major localised problems"; bracken is identified as the principal cause of vulnerability.
